Description

La présente invention concerne un engin de débarquements/embarquements rapides de charges, telles que notamment du personnel, des véhicules civils ou militaires sur des rivages non aménagés, tout en permettant un transit rapide, par exemple entre un navire en mer et le rivage.The present invention relates to a fast load landings / loadings, such as including personnel, civil or military vehicles on undeveloped shores, while allowing fast transit, for example between a ship at sea and the shore.
A l'heure actuelle, les débarquements entre un navire et une plage sont effectués à l'aide d'engins du type chalands de débarquement, par des engins sur coussin d'air ou à l'aide d'hélicoptères.Currently, landings between a vessel and a range are carried out using gear of the type landing craft by air cushioned craft or using helicopters.
Un navire de débarquement du type chaland présente un faible tirant d'eau permettant un débarquement sur des plages à faible gradient mais il présente l'inconvénient d'une faible vitesse due à ses formes et de capacités évolutives limitées résultant de son faible tirant d'eau et de son fardage important.A barge-type landing ship has a shallow draft allowing landing on low gradient ranges but it has the disadvantage low speed due to its shapes and capacities limited evolution resulting from its shallow draft and its substantial dunnage.
Un navire rapide présente nécessairement un tirant d'eau important qui lui interdit l'approche d'une plage de faible gradient.A fast ship necessarily has a draft important which prevents him from approaching a beach of weak gradient.
Enfin, l'utilisation d'hélicoptères pour assurer le débarquement de véhicules à partir d'un navire nécessite l'utilisation de navires spécialisés munis d'une plateforme et, d'autre part, leur charge est limitée ce qui constitue un inconvénient majeur lorsqu'il s'agit de débarquer des blindés, notamment des chars.Finally, the use of helicopters to ensure the disembarking vehicles from a ship requires the use of specialized vessels equipped with a platform and, on the other hand, their load is limited this which is a major drawback when it comes to land armored vehicles, especially tanks.
La présente invention s'est fixée pour objectif de réaliser un engin de débarquement qui se caractérise, d'une part, par une vitesse de transit importante et, d'autre part, par son aptitude à débarquer des charges sur des plages de faible gradient.The present invention has set itself the objective of make a landing craft that is characterized, on the one hand, by a significant transit speed and, on the other hand, by its ability to land loads on low gradient ranges.
En conséquence, cette invention a pour objet un engin pour embarquements/débarquements de charges, notamment de personnel, de véhicules, sur des rivages non aménagés, du type catamaran, caractérisé en ce que :
  • entre les deux coques latérales dudit catamaran est placée une plateforme mobile, cette plateforme étant réalisée sous la forme d'un caisson étanche dont la partie supérieure supporte les charges en formant une surface de roulement, une rampe déployable étant prévue à chaque extrêmité de ladite plateforme, cette dernière et lesdites rampes en position déployée constituant un couloir de chargement, de largeur uniforme égale à l'espacement entre les deux coques, et
  • on prévoit des mécanismes permettant de faire varier la position relative de ladite plateforme mobile et desdites coques du catamaran de telle sorte que l'engin flotte, soit par l'intermédiaire des seules coques du catamaran, soit par l'intermédiaire de toute la surface de ladite plateforme et desdites coques.
Consequently, the subject of this invention is a machine for loading / unloading loads, in particular of personnel, of vehicles, on undeveloped shores, of the catamaran type, characterized in that:
  • between the two side hulls of said catamaran is placed a mobile platform, this platform being produced in the form of a watertight box whose upper part supports the loads by forming a rolling surface, a deployable ramp being provided at each end of said platform , the latter and said ramps in the deployed position constituting a loading passage, of uniform width equal to the spacing between the two shells, and
  • mechanisms are provided for varying the relative position of said mobile platform and said hulls of the catamaran so that the craft floats, either through the hulls of the catamaran alone, or through the entire surface of said platform and said shells.
Selon un mode de réalisation de l'invention, lesdits mécanismes sont réalisés de la façon suivante :
  • les deux coques latérales dudit catamaran sont reliées en partie haute et à chacune de leurs extrêmités respectives par des poutres et
  • on prévoit des moyens de levage permettant d'amener ladite plateforme respectivement en position haute ou position de transit et en position basse, ou position de débarquement/embarquement, dans laquelle ladite plateforme apporte un complément de flottabilité assurant une diminution du tirant d'eau de l'engin.
According to one embodiment of the invention, said mechanisms are produced in the following manner:
  • the two side hulls of said catamaran are connected in the upper part and at each of their respective ends by beams and
  • lifting means are provided making it possible to bring said platform respectively to the high position or transit position and to the low position, or landing / boarding position, in which said platform provides additional buoyancy ensuring a reduction in the draft of the craft.
Selon la présente invention, les deux coques peuvent en outre être reliées, en partie basse, par des traverses ou poutres profilées, de préférence en forme d'ailes, le caisson constituant ladite plateforme mobile étant réalisé de manière qu'en position basse lesdites traverses viennent s'encastrer sous la surface inférieure dudit caisson selon la présente invention des volets mobiles peuvent éventuellement être disposés dans lesdites traverses profilées de manière à ajuster l'assiette de navigation en fonction du centrage des masses et des conditions de mer, ces volets pouvant en outre être utilisés comme dispositifs de stabilisation pour des transits rapides en mer agitée.According to the present invention, the two shells can in addition to being connected, in the lower part, by crosspieces or profiled beams, preferably wing-shaped, the box constituting said mobile platform being produced so that in the lower position said crosspieces come to be embedded under the lower surface of said casing according to the present invention movable shutters may optionally be arranged in said profiled sleepers so as to adjust the trim navigation according to the centering of the masses and sea conditions, these components can also be used as stabilization devices for fast transits in rough seas.
Selon une autre caractéristique de la présente invention, les moyens de levage de la plateforme sont du type à guidage mécanique par bras articulés, avec verrouillage en positions haute et basse et à commande bi-directionnelle.According to another characteristic of the present invention, the platform lifting means are of the mechanical guidance by articulated arms, with locking high and low positions and bi-directional control.
Selon l'invention, les moyens de guidage de la plateforme mobile peuvent être réalisés sous la forme d'un système de guidage mécanique sur rails, ou à l'aide de chaínes ou de tout autre système approprié.According to the invention, the means for guiding the platform mobile can be realized in the form of a system of mechanical guidance on rails, or using chains or any other appropriate system.
Selon l'invention, le verrouillage en position haute ou basse de la plateforme peut être constitué d'un système de broches ou de consoles éventuellement escamotables, ou de verrous mécaniques.According to the invention, the locking in the high position or platform bass can be made up of a system of possibly retractable pins or brackets, or mechanical locks.
D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent un mode de réalisation dépourvu de tout caractère limitatif. Sur les dessins :

  • la figure 5 est une vue en perspective similaire aux figures 3 et 4 représentant l'engin sans la plateforme mobile, et
  • la figure 6 est une vue de face de l'engin, objet de l'invention.
Other characteristics and advantages of the present invention will emerge from the description given below with reference to the accompanying drawings which illustrate an embodiment devoid of any limiting character. In the drawings:
  • Figures 1 and 2 are schematic elevational views respectively representing the machine according to the present invention in transit position and landing position;
  • FIGS. 3 and 4 show in perspective the object of the invention respectively in the transit position and in the landing position and

En se référant aux dessins on voit que l'engin objet de la présente invention se présente sous la forme d'un catamaran dont les deux coques 10 et 12 sont reliées à chacune de leurs extrêmités, et en partie supérieure, par des poutres 11 et 13. On réalise ainsi une structure permettant d'assurer la rigidité de l'ensemble indépendamment de la plateforme mobile 15 décrite ci-après. Dans l'exemple de réalisation représenté sur les dessins les deux coques 11 et 12 sont en outre reliées, en partie basse et à chacune de leurs extrêmités respectives par des traverses basses profilées 16 et 17, au niveau de la quille profilée des coques 10 et 12, ces traverses 16 et 17 étant de préférence en forme d'ailes de manière à développer des effets de portance partielle assurant des vitesses relativement élevées. Ces traverses 16 et 17 peuvent être munies de volets mobiles 21 ainsi qu'on peut le voir sur la figure 6 de façon à pouvoir ajuster l'assiette de navigation en fonction du centrage des masses et des conditions de mer. Ces volets peuvent en outre être utilisés en tant que dispositifs de stabilisation pour assurer les transits rapides notamment en mer agitée.Referring to the drawings, it can be seen that the object of the present invention is in the form of a catamaran whose two hulls 10 and 12 are connected to each of their ends, and in the upper part, by beams 11 and 13. A structure is thus produced ensuring the rigidity of the assembly independently of the mobile platform 15 described below. In the embodiment shown on the drawings the two shells 11 and 12 are also connected, in lower part and at each of their respective ends by low profile sleepers 16 and 17, at the profiled keel of hulls 10 and 12, these crosspieces 16 and 17 preferably being in the form of wings so as to develop partial lift effects ensuring relatively high speeds. These sleepers 16 and 17 can be fitted with movable flaps 21 as can be see it in figure 6 so you can adjust the navigation trim according to the centering of masses and sea conditions. These components can in addition to being used as stabilization to ensure rapid transits in particular in rough seas.
La plateforme mobile 15, réalisée sous la forme d'un caisson étanche, est positionnée entre les deux coques 10 et 12 et elle est constituée d'un caisson étanche dont la partie supérieure forme une surface de roulement supportant la charge représentée sur les figures 1 à 5 par des blindés et sur la figure 6 par des camions. A chacune des extrêmités de la plateforme mobile 15 on prévoit une rampe déployable respectivement 18, 19 de façon que la plateforme 15 et les rampes 18, 19 constituent un couloir de chargement de largeur uniforme égale à l'espacement entre les deux coques 10 et 12 (voir la figure 4). De préférence, les rampes sont du type portefeuille. En position repliée elles protègent des vagues et des embruns les charges transportées par l'engin (voir la figure 3).The mobile platform 15, produced in the form of a waterproof case, is positioned between the two shells 10 and 12 and it consists of a watertight box, the upper part forms a rolling surface supporting the load shown in Figures 1 to 5 by tanks and in Figure 6 by trucks. To each from the ends of the mobile platform 15 a deployable ramp 18, 19 respectively so that the platform 15 and the ramps 18, 19 constitute a corridor loading width of equal width between the two shells 10 and 12 (see Figure 4). Of preferably, the ramps are of the wallet type. In folded position they protect from waves and spray the loads transported by the machine (see Figure 3).
Lorsque les coques 10 et 12 sont reliées en partie basse par des traverses telles que 16 et 17 (figure 5) ces dernières, lorsque la plateforme mobile 15 est en position basse, viennent s'encastrer sous la surface inférieure de la plateforme, ce qui assure leur protection lors du "plageage" (voir la figure 2).When the shells 10 and 12 are connected in the lower part by sleepers such as 16 and 17 (Figure 5) these last, when the mobile platform 15 is in position low, come to be embedded under the lower surface of the platform, which ensures their protection during "plaging" (see Figure 2).
L'engin comporte en outre des moyens de levage représentés schématiquement en 20 et 20' sur les figures qui sont conçus de manière à permettre d'amener la plateforme 15 respectivement en position haute ou position de transit et en position basse ou position de débarquement/embarquement, position dans laquelle le caisson constituant la plateforme apporte un complément de flottabilité assurant une réduction du tirant d'eau, permettant l'accès au rivage.The machine further comprises lifting means shown schematically in 20 and 20 'in the figures which are designed to allow the platform 15 to be brought respectively in high position or transit position and low position or disembarkation / embarkation, position in which the box constituting the platform provides additional buoyancy ensuring a reduction in the draft, allowing access to shore.
Selon un exemple de réalisation de ces moyens de levage, ceux-ci peuvent être du type à guidage mécanique par bras articulés, avec verrouillage en positions haute et basse et à commande bi-directionnelle. Cette commande bi-directionnelle peut être obtenue, par exemple à l'aide de vérins double effet ou à l'aide d'un système du type vis sans fin-crémaillère. Les déplacements de la plateforme sont commandés à partir du poste de pilotage.According to an exemplary embodiment of these lifting means, these can be of the type with mechanical guidance by arm articulated, with locking in high and low positions and bi-directional control. This bi-directional control can be obtained, for example using double acting cylinders or using a screw type system endless rack. The displacements of the platform are controlled from the cockpit.
Dans l'exemple de réalisation illustré par la figure 6, on a représenté en 24 le système de guidage de la plateforme mobile 5, celui-ci pouvant être constitué par un système de guidage mécanique sur rails, ou par des bras articulés comme mentionné ci-dessus ou bien par des chaínes ou par tout dispositif approprié. Sur cette même figure 6 on a schématisé les dispositifs de verrouillage en position haute 22 ou basse 23 de la plateforme mobile 15. Ces dispositifs peuvent être réalisés sous la forme de broches ou de consoles, éventuellement escamotables ou de verrous mécaniques ou de tout système approprié.In the embodiment illustrated by FIG. 6, we represented at 24 the platform guidance system mobile 5, which can be constituted by a system mechanical guidance on rails, or by articulated arms as mentioned above either by chains or by any suitable device. On this same figure 6 we have schematically the locking devices in position high 22 or low 23 of the mobile platform 15. These devices can be made in the form of pins or consoles, possibly retractable or locks mechanical or any suitable system.
Selon l'invention, la commande bi-directionnelle mentionnée ci-dessus représentée schématiquement en 25 sur la figure 6 peut être réalisée sous la forme de vérins à double effet agissant directement sur la plateforme mobile 15 ou par l'intermédiaire des bras articulés mentionnés ci-dessus, ou bien par des crémaillères ou des treuils actionnant des câbles ou bien encore à l'aide de moto-réducteurs entrainant des chaínes. On peut encore dans ce but, utiliser en combinaison les systèmes mentionnés ci-dessus ou tout autre moyen de commande bi-directionnelle de puissance.According to the invention, the bi-directional control mentioned above shown schematically at 25 on Figure 6 can be realized in the form of cylinders to double effect acting directly on the mobile platform 15 or via the articulated arms mentioned above, or by racks or winches actuating cables or even using geared motors causing chains. We can still in this purpose, use in combination the above mentioned systems or any other means of bi-directional control power.
La propulsion est assurée de préférence par des hydrojets avec tuyère directionnelle et bec d'inversion assurant une excellente manoeuvrabilité et des distances d'arrêt très courtes. Ces hydrojets, non représentés sur les dessins sont disposés symétriquement dans les deux coques latérales 10 et 12, sensiblement au-dessus du fond de ces dernières. On peut en outre prévoir des propulseurs latéraux, à l'avant des coques afin de faciliter le contrôle latéral de l'engin.Propulsion is preferably provided by hydrojets with directional nozzle and reversing nozzle ensuring excellent maneuverability and very stopping distances short. These hydrojets, not shown in the drawings are arranged symmetrically in the two shells side 10 and 12, substantially above the bottom of these past. It is also possible to provide propellants side, in front of the hulls to facilitate the lateral control of the machine.
En transit (figures 1 et 3) l'engin selon l'invention présente une configuration de navigation sur ses deux coques profilées 10 et 12 permettant une vitesse élevée même en mer formée. La charge est portée sur la plateforme 15 positionnée en haut des coques et elle est protégée par les rampes avant et arrière 18 et 19.In transit (Figures 1 and 3) the machine according to the invention presents a navigation configuration on both profiled hulls 10 and 12 allowing high speed even in heavy seas. The load is carried on the platform 15 positioned at the top of the hulls and it is protected by the front and rear ramps 18 and 19.
A l'approche de la plage (figures 2 et 4) la plateforme 15 est abaissée au niveau de la partie inférieure des coques 10 et 12 et dans cette position elle apporte à l'engin un complément de flottabilité permettant une réduction du tirant d'eau à une valeur suffisamment faible pour permettre d'accéder en lisière de plage, la rampe telle que 18 étant alors déployée afin de permettre le débarquement de personnel et des véhicules de façon classique.Approaching the beach (Figures 2 and 4) platform 15 is lowered at the bottom of the hulls 10 and 12 and in this position it brings to the machine a additional buoyancy allowing a reduction in draft at a value low enough to allow access to the edge of the beach, the ramp such that 18 then being deployed in order to allow the disembarking personnel and vehicles so classic.
Comme on le comprend la plateforme 15 et ses rampes 18 et 19 constituent un couloir de chargement de largeur uniforme s'adaptant à une configuration en file d'engins dans le radier d'un transport de chalands.As we understand the platform 15 and its ramps 18 and 19 constitute a wide loading lane uniform adapting to a configuration in line of machines in the raft of a barge transport.
Le dispositif, objet de l'invention, peut être utilisé pour tout transport rapide, de personnes, de matériels, de véhicules, par voie maritime ou fluviale tel que par exemple :
  • transport de matériel de protection de l'environnement permettant d'apporter en tout point d'un littoral ou de berges fluviales, des engins de protection civile;
  • transport pour des actions humanitaires sur un rivage non aménagé;
  • transport et débarquement de matériels et personnels militaires;
  • transport fluvial ou maritime sans installation portuaire ou avec installations limitées ou à très faible tirant d'eau;
  • transport maritime de produits depuis un navire de haute mer vers une rive ou un littoral non équipé d'installations portuaires ou à très faible tirant d'eau.
The device, object of the invention, can be used for any rapid transport of people, materials, vehicles, by sea or river such as for example:
  • transport of environmental protection equipment enabling civil protection equipment to be brought to any point on a coast or riverbanks;
  • transportation for humanitarian actions on an undeveloped shore;
  • transport and disembarkation of military equipment and personnel;
  • river or maritime transport without port facility or with limited facilities or with very shallow draft;
  • sea transport of products from an ocean-going vessel to a shore or coastline not equipped with port facilities or with very low draft.
Les avantages apportés par l'engin objet de l'invention sont notamment les suivants :
  • importante capacité de vitesse de transit même sur mer formée lorsque la plateforme est en position haute;
  • réduction importante du tirant d'eau permettant d'approcher très près la lisière d'une plage, la plateforme de chargement étant en position basse avec sa surface de roulement au-dessus du niveau de l'eau, la présence de la rampe avant réduisant encore la longueur de franchissement de l'eau;
  • excellente manoeuvrabilité en position de transit et en position de débarquement;
  • grande surface de flottaison en mode "plageage" donnant une faible sensibilité au centrage des masses et permettant une grande flexibilité de disposition du chargement;
  • possibilité de prévoir des volets, tels que 21 dans les traverses inférieures profilées, telles que 16 et 17, ces volets étant profilés de façon à ajuster l'assiette de navigation en fonction du centrage des masses et des conditions de mer, et pouvant être utilisés en tant que systèmes de stabilisation.
The advantages provided by the object of the invention are in particular the following:
  • significant transit speed capacity even on sea formed when the platform is in the high position;
  • significant reduction in the draft making it possible to approach very close to the edge of a beach, the loading platform being in the low position with its running surface above the water level, the presence of the front ramp reducing still the length of water crossing;
  • excellent maneuverability in transit position and disembarkation position;
  • large flotation surface in "plaging" mode giving low sensitivity to mass centering and allowing great flexibility of loading arrangement;
  • possibility of providing flaps, such as 21 in the lower profiled crosspieces, such as 16 and 17, these flaps being profiled so as to adjust the navigation trim according to the balance of the masses and sea conditions, and which can be used as stabilization systems.
Il demeure bien entendu que la présente invention n'est pas limitée aux modes de réalisation décrits et/ou mentionnés ci-dessus à titre d'exemples non limitatifs mais qu'elle en englobe toutes les variantes.Of course, the present invention is not not limited to the embodiments described and / or mentioned above by way of nonlimiting examples but that it encompasses all variants.
